Hardware Reference 37
C613-03058-00 REV A
The RS-232 asynchronous serial port (ASYN 0) can be used as a general
purpose port for terminals, printers or modems. The default communications
settings are:
• 9600 bps
• 8 data bits
•1 stop bit
•no parity
•hardware flow control
Power Supply
AT-AR410 and AT-AR410S routers have a universal AC input connector and a
power switch on their rear panel. The routers require a power input of
100-240 VAC and 50–60Hz.
Some interfaces that may be installed in the router are not transformer isolated.
This means they will be referenced to the frame ground of the equipment and
may be damaged if connected to an interface on another piece of equipment
which is at a different ground potential.
AR700 Series Routers
All AR700 Series routers include PIC bays. PIC bays add expansion flexibility
by allowing the installation of PIC cards, which are available with ISDN (PRI
E1/T1, BRI S/T, or BRI U), Ethernet, synchronous, or asynchronous ports.
AR700 Series models are distinguished by the number of ports and presence or
absence of an NSM bay and PAC card slot. Where present, an NSM bay allows
the installation of an NSM, which may have additional ports or up to four PIC
bays. A PAC slot (found on the AR725, AR740, and AR745) allows the
installation of optional compression and or encryption cards, which connect to
the router through a high performance PCI bus
.
